Original Abstract

We report the observation of the sub-milliradiant divergence operation of a capillary discharge soft-X-ray laser, that indicates that X-ray radiation has been amplified in a refraction-guiding plasma active medium. The lasing is produced on the 46.9 nm transition of the Ne-like Ar. The 0.7 mrad divergence, axially peaked-pro. le beam is obtained in the single-pass amplification regime. The comparison of the recorded laser beam profiles with the results of our computer simulations shows that the capillary discharge z-pinch forms an active plasma wave guide, which has the electron density pro. le with depression on its axis. The waveguiding of X-ray radiation and its amplification is demonstrated over a 30 cm long plasma column, where the laser operates in a saturated regime with energy of similar to 50 muJ.
